CYCLE.

SPECIFICATION forming part of Letters Patent N 0. 572,544, datedDecember 8, 1896. Application filed May 4, 1896. Serial No- 590,240. (Nomodel.)

To (ZZZ whom it may concern.-

Be it known that we," Gnone CHRISTIAN WILHELM HIPPERLING and WILHELM AN-TON DIETRICH HIPPERLING, subjects of the Emperor of Germany, andresidents of Wandsbeck-Hamburg, in the Empire of Germany, have inventednew and useful Improvements in Cycles, of which the following is aspecification.

This invention has for its object a contrivance for retaining constant,irrespective of the weight, the distance between the saddle and thepedals on such cycles as have a spring arranged for carrying the saddleas a substitute for the pneumatic tires.

On the drawings, Figure 1 shows a side View of the contrivance, partlyin section; Fig. 2, a front view, partly in section.

The saddle a is fastened on the right-an gled rod 1), by which it can befixed at any desired height in the tube a. The upper part of the tube isinserted into the frame cZ and its lower part into the cross-piece e bymeans of the rod f, bent forward below the latter. Around the tube 0 astrong spiral spring g is placed, the lower end of which presses againstthe plate h, resting on the cross-piece e, and the upper end against theplate h. The latter abuts against the nut Z, which can be screwed up anddown on the tube 0, which is here provided with a thread in order togive the spring 9 tension in proportion to the weight on the saddle a.This spring g serves for taking up the jolting and renders pneumatictires superfluous.

The forwardly-bent anglearn1f' of the rod f is, by means of a bolt k,linked to the like operating-levers Z Z.

of these levers are formed by the bolts m m of the arms at n, fastenedon the frame A,

The points of support while the bolts 0 0 lie in such manner between thebolts m m and the common bolt 70 that forms a proper fraction, that is,m0

must be shorter than 070. The bolts 0 of the levers Z Z are linked withthe common bolt q, lying in the slots 10 in the connecting-rods M. Thisbolt q forms at the same time the fulcrum for the treadle-levers a" 1".The ratio of the free longer arm to the short arm of each of thesetreadle-levers is likewise It is therefore obvious that with any weightoperating on the saddle in consequence of the above-described levertransmission the distance between the saddle a and pedal 8 alwaysremains the same.

The shorter leverarm of the treadle-lever r (or r) is connected in anyknown manner with the crank 15, which is mounted on the shaft 20 of thechain-wheel o.

What we claim is-= In a contrivance for retaining constant the distancebetween the saddle and the pedals of cycles the combination of the twolevers Z Z, linked to the saddle-rod, with the bolt It, the spring g,the stationary bolt m, on which the levers Z Z are turned, the bolts 0,the connecting-rods u, the bolt g, which on the yielding of the saddlea, yields as much as the bolts 0, so that as the lever-arms of the leverZ have the same proportion, as the treadlelever arms, the pedal 3 alwaysremains equidistant from the saddle, as described.
